Description

Technical Field

[0001] This utility model relates to the field of soldering iron technology, and in particular to a soldering iron for soldering and disassembling capacitors and resistors. Background Technology

[0002] Soldering irons are essential tools for electronics manufacturing and appliance repair. They use electric current to heat the soldering tip to a sufficiently high temperature to melt solder. During the soldering process, the molten solder is evenly applied to the pins or wires of the components to be connected, and the soldering tip is used to firmly connect the solder to the pins or wires. This ensures the strength and reliability of the circuit connection and is an indispensable step in electronics manufacturing and repair. In the electronics manufacturing and repair industry, soldering and removing capacitors on PCBs (printed circuit boards) and FPCs (flexible printed circuit boards) is extremely common.

[0003] Traditional single-tip soldering irons have many limitations when handling capacitors. For example, during soldering, it's difficult to ensure that both ends of the capacitor are heated evenly and simultaneously, easily leading to poor soldering conditions such as cold solder joints and bridging. When removing capacitors, the inability to heat both ends synchronously results in uneven removal force, potentially damaging the PCB board or FPC pads and traces. This is especially true for microcapacitors and precision circuit boards, where the difficulty and risk of using traditional soldering irons are even greater. Therefore, this paper proposes a soldering iron that can accurately and efficiently handle capacitor soldering and removal. Utility Model Content

[0004] Based on this, it is necessary to address the aforementioned technical problems by providing a soldering iron for soldering and removing capacitors and resistors. When soldering or removing capacitors, the tips of the first and second soldering iron tips are aligned with the two ends of the capacitor or resistor, respectively. A temperature controller is used to bring the soldering iron tips to a specific temperature. During heating, the two tips of the first and second soldering iron tips evenly heat both ends of the component, causing the solder to melt rapidly. This achieves precise, efficient, and safe soldering and removal of capacitors, effectively ensuring soldering quality and the integrity of the PCB board and FPC. This improves the quality and efficiency of electronic circuit manufacturing and repair. Furthermore, an adjustment component is provided on the mounting base, allowing precise adjustment of the distance between the tips of the first and second soldering iron tips to accommodate capacitors and resistors of various sizes and specifications, easily handling both small surface-mount components and larger through-hole components.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

The top ends of both the first and second handles are rotatably connected to the mounting base, and a spring is installed between the first and second handles. The temperature controller is fixedly connected inside the mounting base and is used to control the heating temperature of the first and second soldering tips. The mounting base is provided with an adjustment component for adjusting the distance between the first and second soldering tips.

[0008] Furthermore, both the first and second soldering iron tips have a pointed tip structure.

[0009] Furthermore, the surfaces of the first and second handles are ergonomically designed.

[0010] Furthermore, it also includes an operation panel, to which the temperature controller is electrically connected.

[0012] Furthermore, a first positioning post and a positioning post are fixedly connected to the side of the first handle and the second handle that are close to each other, and the two ends of the spring are respectively sleeved on the outer surfaces of the first positioning post and the positioning post.

[0013] Furthermore, the adjustment assembly includes an adjustment cylinder and an adjustment screw. The adjustment cylinder is slidably sleeved on the inner wall of the mounting groove. A connecting plate is fixedly connected to the upper surface of the adjustment cylinder. The adjustment screw is rotatably connected to the upper surface of the mounting base through a bearing. A handle is fixedly connected to the top end of the adjustment screw. The bottom end of the adjustment screw passes through the connecting plate and is fixedly connected to a limit block. The adjustment screw is threadedly connected to the connecting plate.

[0014] Furthermore, the adjusting screw is located between the first pin and the second pin, and the outer surface of the handle is provided with anti-slip texture.

[0015] Furthermore, through grooves are provided on both the left and right sides of the bottom end of the adjusting cylinder, and rollers are rotatably connected between the inner walls of the front and rear sides of the through grooves through bearings. The first handle and the second handle are in contact with the left and right rollers respectively.

[0016] Furthermore, the front of the mounting base has an elongated hole communicating with the mounting groove, the front of the adjusting cylinder is fixedly connected to a fixing rod, the front of the fixing rod passes through the elongated hole and is fixedly connected to a pointer, and the front of the mounting base has a scale line corresponding to the pointer along the elongated hole.

[0018] The soldering iron provided by this utility model for soldering and disassembling capacitors and resistors has two heating tips on the soldering iron and a precise temperature control device inside the soldering iron.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background section, traditional single-tip soldering irons have many limitations when dealing with capacitors. For example, during soldering, it is difficult to ensure that both ends of the capacitor are heated evenly at the same time, which can easily lead to poor soldering conditions such as cold solder joints and bridging. When removing capacitors, the inability to heat both ends simultaneously can result in uneven disassembly force, which may damage the pads and circuits of the PCB board or FPC. This is especially true for small capacitors and precision circuit boards, where the operation of traditional soldering irons is more difficult and risky.

[0030] To address this technical problem, this invention provides a soldering iron for soldering and disassembling capacitors and resistors. A temperature controller 5 maintains the soldering iron tip at a specific temperature. During heating, the first soldering tip 202 and the second soldering tip 302 evenly heat both ends of the component, rapidly melting the solder. This enables precise, efficient, and safe soldering and disassembly of capacitors, effectively ensuring soldering quality and the integrity of the PCB board and FPC. This improves the quality and efficiency of electronic circuit manufacturing and repair. Furthermore, an adjustment component 6 is provided on the mounting base 1, allowing precise adjustment of the tip spacing between the first soldering tip 202 and the second soldering tip 302, accommodating capacitors and resistors of various sizes and specifications. It can easily handle both small surface-mount components and larger through-hole components.

[0031] For details, please refer to Figure 1-6 Soldering irons used for soldering and removing capacitors and resistors specifically include:

[0032] Mounting base 1, first soldering iron 2 and second soldering iron 3, the first soldering iron 2 includes a first handle 201 and a first soldering tip 202, the second soldering iron 3 includes a second handle 301 and a second soldering tip 302, the top ends of the first handle 201 and the second handle 301 are rotatably connected to the mounting base 1, and a spring 4 is installed between the first handle 201 and the second handle 301.

[0033] Temperature controller 5 is fixedly connected inside the mounting base 1. Temperature controller 5 is used to control the heating temperature of the first soldering tip 202 and the second soldering tip 302. The mounting base 1 is provided with an adjustment component 6, which is used to adjust the distance between the first soldering tip 202 and the second soldering tip 302.

[0034] The soldering iron provided by this utility model for soldering and disassembling capacitors and resistors allows for precise adjustment of the tip distance between the first soldering tip 202 and the second soldering tip 302 during capacitor soldering or disassembly operations. The tips are aligned with the two ends of the capacitor or resistor, respectively. A temperature controller 5 maintains the temperature of the soldering tip at a specific value. During heating, the two tips of the first and second soldering tips 202 and 302 evenly heat the two ends of the component, rapidly melting the solder. This enables precise, efficient, and safe soldering and disassembly of capacitors, effectively ensuring soldering quality and the integrity of the PCB board and FPC. This improves the quality and efficiency of electronic circuit manufacturing and repair. Furthermore, an adjustment component 6 is provided on the mounting base 1, allowing for precise adjustment of the tip distance between the first and second soldering tips 202 and 302, accommodating capacitors and resistors of various sizes and specifications. It can easily handle both small surface-mount components and larger through-hole components.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1

[0039] Please refer to Figure 1-6A soldering iron for soldering and disassembling capacitors and resistors includes a mounting base 1, a first soldering iron 2, and a second soldering iron 3. The first soldering iron 2 includes a first handle 201 and a first soldering tip 202. The second soldering iron 3 includes a second handle 301 and a second soldering tip 302. The top ends of the first handle 201 and the second handle 301 are rotatably connected to the mounting base 1. A spring 4 is installed between the first handle 201 and the second handle 301. When the first handle 201 and the second handle 301 are squeezed and force is applied, the first soldering tip 202 and the second soldering tip 302 move closer to each other and compress the spring 4. After releasing, the restoring force of the spring 4 causes the first soldering tip 202 and the second soldering tip 302 to open.

[0040] Temperature controller 5 is fixedly connected inside the mounting base 1. Temperature controller 5 is used to control the heating temperature of the first soldering tip 202 and the second soldering tip 302. By setting two heating tips on the soldering iron and providing a precise temperature control device inside the soldering iron, the first soldering tip 202 and the second soldering tip 302 can be rapidly heated to the set temperature and maintained stably. The mounting base 1 is provided with an adjustment component 6, which is used to adjust the distance between the first soldering tip 202 and the second soldering tip 302.

[0041] The soldering iron provided in this embodiment for soldering and removing capacitors and resistors allows for precise, efficient, and safe soldering and removal of capacitors and resistors. The first soldering tip 202 and the second soldering tip 302 are aligned with the two ends of the capacitor or resistor, respectively. A temperature controller 5 ensures the soldering tip reaches a specific temperature. During heating, the two tips of the first and second soldering tips 202 and 302 heat the two ends of the component evenly, rapidly melting the solder. This ensures accurate, efficient, and safe soldering and removal of the capacitor, effectively guaranteeing soldering quality and the integrity of the PCB board and FPC. This improves the quality and efficiency of electronic circuit manufacturing and repair. Furthermore, an adjustment component 6 is provided on the mounting base 1, allowing for precise adjustment of the tip spacing between the first and second soldering tips 202 and 302. This adapts to capacitors and resistors of various sizes and specifications, easily handling both small surface-mount components and larger through-hole components. The soldering iron can be operated flexibly on both high-density PCB boards and relatively complex FPC structures, greatly expanding its application range in different electronic equipment manufacturing and repair scenarios.

[0042] Example 2

[0043] The soldering iron for soldering and desoldering capacitors and resistors provided in Embodiment 1 has been further optimized, specifically, as follows: Figure 1 and Figure 2As shown, both the first soldering tip 202 and the second soldering tip 302 have pointed tips. This design allows for better clamping of smaller capacitors and resistors. The two pointed tips enable precise positioning of the two ends of the capacitor or resistor, ensuring that heat is applied evenly and synchronously to the connection between the component leads and the pads during soldering or disassembly. This not only allows for quick removal or soldering of resistors and capacitors but also significantly improves operational accuracy, effectively reducing problems such as cold solder joints, false solder joints, pad lifting, and component damage caused by uneven heat. This significantly increases the first-time success rate of soldering and disassembly, thereby improving overall work efficiency.

[0044] The surfaces of the first handle 201 and the second handle 301 are ergonomically designed. Because the first handle 201 and the second handle 301 are ergonomically designed, they are easy for operators to hold and apply force, reducing fatigue during long-term operation. The system also includes an operation panel 7, and the temperature controller 5 is electrically connected to the operation panel 7. The temperature of the soldering iron is determined according to the capacitor, resistor and board material being processed, and can be preset on the operation panel 7, which is very convenient.

[0045] Example 3

[0046] The soldering iron for soldering and desoldering capacitors and resistors provided in Embodiment 1 or 2 is further optimized, such as... Figure 3 and Figure 4 As shown, the lower surface of the mounting base 1 is provided with a mounting groove 101. The top ends of the first handle 201 and the second handle 301 are rotatably connected to the inner walls of the front and rear sides of the mounting groove 101 through the first pin 102 and the second pin 103, respectively. The first positioning post 203 and the positioning post 303 are fixedly connected to the side of the first handle 201 and the second handle 301 that are close to each other. The two ends of the spring 4 are respectively sleeved on the outer surfaces of the first positioning post 203 and the positioning post 303. The spring 4 is limited by the first positioning post 203 and the positioning post 303 to better hold the first handle 201 and the second handle 301 and prevent the spring 4 from falling off.

[0047] Example 4

[0048] To adjust the opening angle and more accurately clamp resistors or capacitors, the soldering irons for soldering and removing capacitors and resistors provided in the above embodiments have been further optimized, such as... Figure 4 and Figure 5As shown, the adjustment assembly 6 includes an adjustment cylinder 601 and an adjustment screw 602. The adjustment cylinder 601 is slidably sleeved on the inner wall of the mounting groove 101. A connecting plate 603 is fixedly connected to the upper surface of the adjustment cylinder 601. The adjustment screw 602 is rotatably connected to the upper surface of the mounting base 1 through a bearing. A handle 604 is fixedly connected to the top of the adjustment screw 602. The bottom end of the adjustment screw 602 passes through the connecting plate 603 and is fixedly connected to a limit block 605. The adjustment screw 602 is threadedly connected to the connecting plate 603. The adjustment screw 602 is located between the first pin 102 and the second pin 103. The outer surface of the handle 604 is provided with anti-slip texture. Through grooves 606 are provided on both the left and right sides of the bottom end of the adjustment cylinder 601. Rollers 607 are rotatably connected between the inner walls of the front and rear sides of the through grooves 606 through a bearing. The first handle 201 and the second handle 301 are in contact with the left and right rollers 607 respectively.

[0049] When it is necessary to reduce the distance between the first soldering tip 202 and the second soldering tip 302, turn the handle 604 to drive the adjusting screw 602 to rotate. Since the adjusting screw 602 is threadedly connected to the connecting plate 603, the adjusting screw 602 can drive the connecting plate 603 and the adjusting cylinder 601 to move downward during the rotation. During the downward movement, the adjusting cylinder 601 can squeeze the first handle 201 and the second handle 301 through the roller 607, so that the first handle 201 and the second handle 301 rotate around the first pin 102 and the second pin 103 respectively, thereby reducing the distance between the first soldering tip 202 and the second soldering tip 302 at the bottom. When the distance between the first soldering tip 202 and the second soldering tip 302 is increased, turn the handle 604 in the opposite direction. The restoring force of the spring 4 increases the distance between the first soldering tip 202 and the second soldering tip 302, thereby accurately adjusting the opening angle. When looking for smaller components to clamp, it is not necessary to hold the handle for a long time.

[0050] like Figure 1 and Figure 2 As shown, the front of the mounting base 1 has an elongated hole 11 communicating with the mounting groove 101. A fixing rod 12 is fixedly connected to the front of the adjusting cylinder 601. The front of the fixing rod 12 passes through the elongated hole 11 and is fixedly connected to a pointer 13. A scale line 14 corresponding to the pointer 13 is opened along the elongated hole 11 on the front of the mounting base 1. With this structural design, when adjusting the distance between the first soldering iron tip 202 and the second soldering iron tip 302, the adjusting cylinder 601 will drive the fixing rod 12 and the pointer 13 to move. The distance to be adjusted can be judged by the position of the pointer 13 on the scale line 14, resulting in better performance.

[0051] The soldering iron for soldering and disassembling capacitors and resistors provided by this utility model is used as follows:

[0052] By setting two heating tips on the soldering iron and incorporating a precise temperature control device inside, the first soldering tip 202 and the second soldering tip 302 can be rapidly heated to the set temperature and maintained stably. Simultaneously, the distance between the two tips (first soldering tip 202 and second soldering tip 302) can be finely adjusted according to different capacitor and resistor sizes and PCB / FPC layouts. When removing capacitors or resistors, the simultaneous heating and balanced force application of both tips significantly reduces mechanical and thermal stress damage to the PCB or FPC compared to traditional single-tip soldering irons. This effectively protects the circuit integrity and solder pad adhesion of the circuit board, reduces irreversible damage to the circuit board during repair or component replacement, extends the lifespan of the circuit board, and lowers production costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
